.NET Framework 4.0 problem

[Andrew]

After installing .NET Framework 4.0 (with Visual Studio 2010 beta 2) I couldn't load my plugins written in .NET 3.5. LCD Smartie shows this error:

Code: Select all

---------------------------
LCD Smartie
---------------------------
Load of plugin failed: Plugin Monitor.dll had an exception during Init: External exception E0434F4D
---------------------------
OK   
---------------------------

On my LCD is something like this:

Code: Select all

[Dll: No Bridge Func]

I've tried to rebuild my plugins in VS 2010 but still the same error....

Any ideas?

[limbo]

I'm going to test it....
although I'm afraid that Microsoft does good job out there I believe that something is not supported on the new version...

I'll "hit you" back with my results

[Andrew]

I don't know where to start. After uninstalling .NET Framework 4.0 all works fine. Code is still the same.

I've noticed one thing - plugins are working in the background but they can't return any string to LCD Smartie.

[limbo]

I didn't tested yet, but can you check the following?

Try to create a brand new project and select framework 3.0 from visual studio menu, then add source code from a well working plugin to this project and compile it.
What is the result?

[Andrew]

Still the same problem. I've created a .NET 2.0 and 3.0 project, compiled it and run under LCD Smartie.

[limbo]

I just created a new plugin on visual studio 2010 beta 2
it seems to work fine for me

I attach the source and the compiled plugin as well

Give it a try

[Andrew]

Well....it's in VB and my is in C#. Could you try this?

[limbo]

I just tried the compiled dll... works like a charm!

look the third line on the following image

[Andrew]

The third line contains a polish char so it's normal

So I see that something is wrong with my system (Win 7 Pro)....but I'll try to repair it somehow....thanks a lot!

On a clean installation of Windows 7 and VS2010 I have the same error :/ Could someone with Win 7 and VS2010 check this?

[limbo]

Just tested windows 7 and VS2010 and I get error in every plugin I use.... This seems to be something caused by Framework 4.
I'll make some tests more and hit you back with the results

Update: Removing Framework 4 beta seems to fix the plugin problem. Unfortunately Visual Studio is not loading after that (which seems to be a normal behaviour while an essential part is missing)

I know that But for me, it's not an solution...

I saw, that after installing .NET 4.0, 3.5 is missing (but other programs written for 3.5 are workin'). Also, .NET 2.0 has something called NGEN, in 3.5 it's missing, but in 4.0 it's in the system.

[limbo]

But for me, it's not an solution...

for me either
I 'm going back to Visual Studio 2008 until the final 2010 release.

[Andrew]

OK. I have an solution from MS Connect:

There's not much we can do now about the runtime activation implementation in 4.0. It may be possible to work around the Windows behavior with a hack but given where we are in the product cycle this is very unlikely to happen.

However, if you don't mind running LCD Smartie managed plugins in .NET 4.0, you can configure the app so by adding the following config file (named LCDSmartie.exe.config):

<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" />
</startup>
</configuration>

Also you can read other solutions

Hi All,
Ive been having the same issue trying to load plugins into LCD smartie on my end too.
I've managed to trace the problem to DNBridge.dll. My theory is that microsoft might have changed some internal representation of classes or functions or something in their latest version.

I managed to solve this issue by recompiling DNBridge myself from source.
Ive attached the version I compiled with Visual Studio 2010, and on Windows 7.
In addition, the source code is available here:
http://www.axcis.com.au/bb/viewtopic.php?t=82
if you would like to recompile yourself.

Please confirm that solved the issue for you too...
Thanks

Thats Great news!
Although it causes errors on XP with 3.5 framework, I think its a solution on (Windows 7) framework 4 based systems... I have to try it
Thanks for your support! Keep on Pal

Thanks for the hard work; unfortunately, your new DLL ends up crashing LCD Smartie once my plugin loads. :/

I'm running out of options here. None of the existing performance plugins available can handle all performance counters under Windows 7 64-bit, and I can't get my own to interface with LCD Smartie without the dreaded "No Bridge Func" message.

Any other suggestions?

Coming back with more bad news... Microsoft released an update few days ago which seems to cause all plugins (.net based) to crash on windows 7. So now any updated Win7 PC should not be able to load .net based plugins...

Hey, Im testing on my PC, with windows 7, fully updated, using a recompiled DNBridge and I'm afraid I cannot replicate the issue. It all seems to be working fine for me...

[limbo]

maybe it caused by visual studio updates... I'll take a closer look during next days about the latest updates installed on my PC... and i will inform you

Edit:
I'm back with some screen shots from my system:
